Final answer:
To write a balanced nuclear equation, you list reactants and products conserving the number of protons and neutrons. Examples include positron emission from Carbon-11 and beta decay of Molybdenum-99 with their respective balanced equations.
Step-by-step explanation:
Writing a balanced nuclear equation involves detailing the reactants and products of a nuclear reaction while ensuring that the numbers of protons and neutrons are conserved. Here are the balanced equations for the provided reactions:
- a. Positron Emission of Carbon-11 (11C):
^{11}_6C → ^{11}_5B + ^{0}_{+1}e - b. Beta Decay of Molybdenum-99 (99Mo):
^{99}_{42}Mo → ^{99}_{43}Tc + ^{0}_{-1}e - c. Alpha and Gamma Emission: The equation will depend on the parent isotope that was not provided in the question.
- d. Fusion reaction example might involve deuterium and tritium:
^2_1H + ^3_1H → ^4_2He + ^1_0n + Energy
To balance the equations, always ensure that both the mass numbers (top number) and atomic numbers (bottom number) are balanced on each side of the equation, accounting for all particles emitted or absorbed.
